The FC D_id and S_id fields in teh FC frame encapsulated inside iFCP unfortunately has "undefined" (semi-random) values so we can not use th S_/D_id matching in FC when transported atop iFCP.
Change iFCP to call a new fc_ifcp handler instead of the fc handler.
Add a new handler to FC specific to iFCP.
Only set the pinfo->src/dst fields to the S_id/D_id fields IFF the FC frame was NOT transported ontop of iFCP.
Othervise we just use the TCP/IP values that are already stored there.
Some Hosts use RelativeOffset fields for FC. We can only dissect the RelOff field with offset 0.
Change FC to only call the FCP subdissector if offset==0 when relative offsets are used.
Some hosts when using relative offsets do not specify a proper value for rxid in teh commands instead htey lkeave it as 0xffff
Change the FCP conversation matching to ignore RXID when searching for a conversation.
